the thing about investing in real estate fline, or investing in general, is to find the gems. if you spend all your time saying that you "can't" do things, then that will ultimately be the case.
i live in NY, long island, so i feel your pain, but you've got to figure it out. you have to get into the habit of figuring things out, so that you can move past the "can't do's".
there's alot more to this business than just knowing numbers.
once you get the numbers down (2 - 6 months depending on how fast of a learner you are) - then the next step will be uping the ante...moving past just numbers to the next level.
it's all about action. the more you take of it, the better and more able you will be able to be successful. "action" doesn't mean flying off the handle, personally guaranteeing loans and "going for it" either.
be methodical. get yourself a schedule for devoting time to rei. figure things out and just keep going.
